Area of Science:

  • Materials Science
  • Manufacturing Engineering
  • Non-Destructive Testing

Background:

  • Laser powder deposition (LPD) is a key additive manufacturing technique for creating 3D parts and repairing components.
  • Current methods lack in-process, non-destructive flaw detection for LPD products.
  • Ensuring component integrity during manufacturing is critical for high-value applications.

Purpose of the Study:

  • To propose and validate a novel laser ultrasonic (LU) technique for in-line, non-destructive inspection of LPD components.
  • To establish the sensitivity of the LU technique for detecting manufacturing-induced flaws.
  • To demonstrate the feasibility of the LU technique for real-time quality control in LPD.

Main Methods:

  • Manufacturing of Inconel reference samples with precisely machined flaws.
  • Development and application of a laser ultrasonic technique for in-line inspection.
  • Creation of numerical models for laser-generated ultrasonic waves to optimize setup and understand physics.
  • Experimental validation using reference samples and deposition samples with induced flaws.

Main Results:

  • The laser ultrasonic technique demonstrated sensitivity to machined flaws in Inconel samples.
  • Numerical models provided insights into wave propagation and aided experimental setup optimization.
  • A proof-of-concept prototype successfully detected induced flaws in specific LPD samples.
  • Detected flaws were consistent with those found using ultra-high sensitivity X-ray techniques.

Conclusions:

  • The proposed laser ultrasonic technique is capable of detecting typical micro-defects in LPD components during manufacturing.
  • This non-destructive, in-line inspection method can identify near-surface and surface flaws in single-layer deposits.
  • The LU technique offers a promising solution for quality assurance in additive manufacturing processes like LPD.
